Description
GUPnPSearchCriteriaParser parses ContentDirectory search criteria strings.
Note that no signals will be emitted if a wildcard is specified, and that the user is responsible for ensuring precedence of conjunction over disjunction.

gupnp_search_criteria_parser_new ()
GUPnPSearchCriteriaParser * gupnp_search_criteria_parser_new
(void
);
Returns : |
A new GUPnPSearchCriteriaParser object. |
gupnp_search_criteria_parser_parse_text ()
gboolean gupnp_search_criteria_parser_parse_text (GUPnPSearchCriteriaParser *parser
,const char *text
,GError **error
);
Parses text
, emitting the various defined signals on the way. If an
error occured error
will be set.
|
A GUPnPSearchCriteriaParser |
|
The search criteria string to be parsed |
|
The location where to store the error information if any, or NULL |
Returns : |
TRUE on success. |
Signal Details
The "begin-parens"
signal
void user_function (GUPnPSearchCriteriaParser *parser,
gpointer user_data) : Run Last
The ::begin_parens signal is emitted to mark the beginning of a parenthetical expression.
|
The GUPnPSearchCriteriaParser that received the signal |
|
user data set when the signal handler was connected. |
The "conjunction"
signal
void user_function (GUPnPSearchCriteriaParser *parser,
gpointer user_data) : Run Last
The ::conjuction signal is emitted whenever a conjuction marker (and) is parsed.
|
The GUPnPSearchCriteriaParser that received the signal |
|
user data set when the signal handler was connected. |
The "disjunction"
signal
void user_function (GUPnPSearchCriteriaParser *parser,
gpointer user_data) : Run Last
The ::disjuction signal is emitted whenever a disjuction marker (or&rpar is parsed.
|
The GUPnPSearchCriteriaParser that received the signal |
|
user data set when the signal handler was connected. |
The "end-parens"
signal
void user_function (GUPnPSearchCriteriaParser *parser,
gpointer user_data) : Run Last
The ::end_parens signal is emitted to mark the end of a parenthetical expression.
|
The GUPnPSearchCriteriaParser that received the signal |
|
user data set when the signal handler was connected. |
The "expression"
signal
gboolean user_function (GUPnPSearchCriteriaParser *parser,
gchar *property,
GUPnPSearchCriteriaOp op,
gchar *value,
gpointer error,
gpointer user_data) : Run Last
The ::expression signal is emitted whenever an expression is parsed.
Set error
and return FALSE
if an error occurred.
